HANGER Application filed latch 19, 1330. Serial No. 437,066.

My invention relates to devices for supporting, handling and/or moving ob ects such as doors, merchandise, and other materials.

The main purpose is to provide a construction by means of which an object can he slid along a track and turned readily to a track extendingat an angle to the first track. The object may be a door, window, or other framelike structure, in fact, any object, piece of merchandise, or material wherein it is desired to transport or move some from one location to another.

I have accomplished this object by the use of a hanger having two pairs of rollers arranged with their axes intersecting at an angle corresponding to the angle of the intersecting tracks. These rollers are all of the same diameter in the preferred form and the tracks are provided with horizontal flanges or members spaced apart sufficiently to allow for a non-rotative spindle which is swiveled in a bracket or base member secured to the door or frame which is to be supported. The door may have one or more of these hangers which permit the movement above mentioned. Preferably the hanger is kept in proper alignment by a set of supplementary rollers adapted to coact with the side walls of the supporting tracks.

Fig. 1 is a plan view of a fragment of track having two sections at right angles to each other and showing a door with hangers embodying my invention.

5 Fig. 2 is a front view of a fragment of a door with two hangers attached.

Fig. 3 is a transverse sectional view showing one of the hangers.

Fig. 4 is a plan view showing the junction between two cross-over tracks and showing a single hanger located at the junction point.

Fig. 5 is a fragmentary plan view of two v tracks arranged in T form.

I Fig. 6 is a transverse sectional view showing the apparatus provided with lateral guiding means.

Fig. 7 is a plan view of the same. Fig. 8 is a plan view showing the same mechanism but with the hanger located at a point of crossing between two intersecting tracks.

The track sections have horizontal flanges 7 and vertical flanges 8 with a slot 9 between the horizontal flanges. When the object is to be moved in only one plane the problem of support is comparatively simple, but when the track has two portions intersecting, for instance at right angles, a difliculty is encountered in turning the frame, door, or other no object 10 from one section of the track to the other.

For instance, in Fig. 1 two track sections intersect at point 11 and it has been found very difficult to design a hanger which would turn readily at right angles. In order to solve this problem I have provided a hanger having a body 12 and carrying two pairs of rollers, such as Iii-13 and 1414, which rollers may have any suitable type of bearings preferably ball earings of any suitable type. These rollers are all of the same diameter and the pairs are so dimensioned and proportioned that the rollers 14 travel on the flanges 7 and are partially guided laterally by theflanges 8.

From inspection of Fig. 3 it will be seen that rollers 13 are entirely free from engagement with the track.

The hanger may be partially. guided by a 30 spindle having a square boss or shank 15 which is more or less loosely guided in the slot 9.

The base 16 of the hanger may be made in any suitable form to support whatever object is to be supported as for instance a chain hoist hook etc. In the form shown the base 16 of the hanger is secured to the upper edge of the frame, door or object 10 and provided with a swivel connection with the shank 15 of the hanger. This swivel connection may be provided in various ways and the form shown is merely intended to be a typical diagrammatic representation. The ball bearing race 18 and balls 19 are secured on spindle 17 by nut 17 A cap 20 screwed onto the upper end of the member 16 holds the ball bearing in place.

When 'the door frame or other object is slid to the right as viewed in Fig. 1 and the I ments at rig right hand hanger finally reaches the end of the track, the rollers 14 rest in the slots 21 and 22 while the rollers 13 drop into the slots 23 and 24. The right hand end of the door frame or object can then be pulled forwardly with the square shank 15 the slot 25. When the rollers 13 ride up on the flanges 26 the rollers 14 are lifted clear. The swlveling on the hen er shank of the top of the door permits the cor to turn while the two hangers are being guided in movet angles to each other.

In the track arrangement of Fig. 4 there are four sections 30, 31, 32 and 33 arranged at right angles to each other. It is obvious that w en the hanger reaches the intersection it is self-centered and may be moved in any of the four directions as above described.

In the arrangement of Fig. 5 there is a track 34 with a header 35 intersecting it at the point 36. It will be seen that this is not materially different from the arrangement of Fig. 1 and that a hanger may be moved in any of three directions from the intersection 36.

2 In thle preferredlform as Show; on Sllieet supp ementary a igning or gui 'n ro era are provided. In this case the vertic al shaft 39 carries at its upper end two pairs of plates 40 and 41 between-which are 'sup orted a number of spring pressed rollers a apted to coact with the side walls of the sup orting track. These plates are held in place y suitable means as for instance a nut 42. Two pairs of rollers 43 are supported between the upper plates and provided with shafts 44 guided in slots 45 so as to permit the rollers to move back and forth from right to left as viewed in the drawings. These rollers are pressed apart by the sprin 46.

Another set of rollers 4 is supported between the lower plates 40 and pressed outlvgrdly by means of springs similar to springs With the parts as shown in position of Figs. 6 and 7, the rollers 43 engage the sides 8 of" the guide track or channel sothat the carriage will travel smoothly without woblen the hanger reaches one of the crossin as shown in Fig. 8, the springs force the ro lers outwardly so that they are in position to guide the ban er in its movement along eit er track in eit er direction without binding on the sides "of the flanges. They are, however, in position to occasionally touch the sides of the flanges if the hanger swings unduly. In moving from the position of Fig. 8 toward the right the rollers 47 will engage the side walls 0 the tracks and guide the hanger in its movement from right to left. It should be'understood, however, that these aligning rollers are merely typical of one 'form of device for accomplishing the desired purpose.

ided in means Variations in details may be resorted to without departing from the principle of the invention.
